MEASURING EARTHSHINE:
NEW SATELLITE IMAGES OF EARTH'S REFLECTIVITY TO IMPROVE WEATHER AND CLIMATE MODELS
G02-057 7/9/02 00:02:10
A sensor aboard NASA's Terra satellite is helping scientists map how much sunlight the Earth's surface reflects back upinto the atmosphere, and this new detailed information should help to greatly improve weather and forecast models. The Moderate Resolution Imaging Spectroradiometer (MODIS) now routinely provides daily global and local measurements of albedo, or the total amount of light reflected from Earth's surface out to space. These precise data may allow scientists to better understand and predict how various surface features absorb and reflect solar radiation, which influence both short-term weather patterns and longer-term climate trends.
TAPE CONTENTS:
ITEM (1): Global Reflectivity - Albedo - The MODIS instrument, flying aboard NASA's Terra and Aqua satellites, measures how much solar radiation is reflected by the Earth's surface almost every day over the entire planet. The sequence begins with a truecolor portrait of the planet and dissolves MODIS albedo. Areas colored red show the brightest, most reflective regions; yellows and greens are intermediate values; and blues and violets show relatively dark surfaces. Black indicates no data available and no albedo data are provided over the oceans.

ITEM (2): North Africa - The new MODIS albedo data product reveals in striking detail how widely varied the terrain is across Northern Africa and the Arabian Peninsula. The variation across the land's surface affects how much solar radiation is absorbed and how much is reflected back up into the overlying atmosphere. This new data product should significantly improve weather forecast models for that region.
